Only 33% of “All” energy is used.

In Kwh In 1976 the population was 218,035,164 and in only 35 years the population is 307,006,550. The average U.S. citizen in 1976 consumed roughly 8,500Kwh. The current average U.S. citizen consumes roughly 12,000Kwh. 218,035,164 x 8,500kwh = 1.8 E 12kwh in 1976 307,006,550 x 12,000kwh = 3.7 E 12kwh in 2011 Per capita U.S. double the consumption of energy in only 35 years.

Questions…. How much petroleum would the U.S. save if the U.S. sets a mileage regulation of 10,000miles a year?
14
Things to Know. Driving population between the ages of 16-70. Population between 16-70 is 197,500,00. Average miles driven: 13,500. 42 gallons in a barrel. Average mpg for a U.S. car is 20. Price of a barrel is $107. Average petroleum consumption = 18,771,000 barrels/day
15
Equations…. 13,500miles-10,000=3500miles saved 3,500miles x 197,500,000= 691,250,000,000miles could be saved 6.9125 E 11miles/20mpg=3.4563 E 10gallons could be saved 3.4563 E 10gallons/42gl/barrel= 823,095,238barrels could be saved 823,095,238barrels x 5.8 E 6Btu = 4.774Qbtus could be saved
16
More Equations… Percent of energy saved for U.S. petroleum: 4.774QBtu/35.75QBtu = 13.4% How many days worth of oil would be saved a year: 823,095,238barrels / 18,771,000 barrels/day = 43days Money saved by U.S. regulation: 823,095,238barrels x $107per barrel = $88,071,000,000 a year.
17
Assumptions Everyone between the ages of 16-70 drives 13500miles. Oil barrel price averages at $107(current oil price).

Idea's for cutting down the use of energy: – Fixing leaks in your house – Changing light bulbs to compact fluorescent "squiggly bulb" – Close window drapes at night to prevent heat from exiting out the windows. – Plug cell phone, computer, game council chargers into a power strip and turn strip off when not in use.
